2,2-Dimethyl-3-phenyl-3-allylaziridine (Az) reacts with Cramer's complex <2> to give .This new complex is transformed by carbon monoxide into , which can be also prepared starting from <2>.The crystal and molecular structure of this carbonyl species has been fully solved by X-ray diffraction, providing the first example of a complex with bidentate aziridine.The ethylene complex reacts with one equivalent of triphenylphosphine to give .A second equivalent of phosphine does not create a monodentate aziridine, but displaces this ligand.Similar behaviour is observed with the carbonyl complex which gives free aziridine and trans-.
